Hey. For the Phantomtail, only go for its tail, as the name hints I guess haha. But only go for its tail, otherwise it'll continually warp away.
I strongly advise using an Aerial Gear (Not the official name, but it's the one that works exceptionally well in the air).
I would get it down to the last layer or two, and then limit it away.
Sorry I couldn't go more in depth, I didn't have trouble on that one so I never had to adjust anything. But that's what I did and it worked well, hope I could help. Good luck!
